In short: Ketchikan has about 8,000 people and sits in Ketchikan Gateway County. Ketchikan Public Utilities serves the county, averaging 12.48¢ per kWh for homes in 2024 (EIA). Rooftop solar here makes roughly 710 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.
This page covers what is local to Ketchikan: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Alaska energy guide.
Ketchikan at a glance
- Place: Ketchikan, Ketchikan Gateway County, Alaska; about 8,033 residents (Census Bureau estimate, July 2024).
- Utility: Ketchikan Public Utilities (city-owned). Homes paid an average 12.48¢ per kWh in 2024 (EIA-861) (utility-wide, not just Ketchikan).
- Sun: 2.43 kWh per square meter per day on average, from 0.35 in December to 4.58 in June (NASA POWER). Our rough estimate: about 710 kWh a year per kW of panels.
- Climate: about 10 cooling degree-days and 7,950 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Top hazards in Ketchikan Gateway County: avalanches “relatively moderate”, landslides “relatively low” and winter weather “relatively low” (FEMA National Risk Index; overall county risk rated “very low”).
Your utility and what it means
Ketchikan Public Utilities is a city-owned utility and served about 6,561 home customers in 2024; its 12.48¢ average was below the 28.83¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
Net metering, export rates and incentives are set at state level and by each utility. Start with the Alaska guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Ketchikan
- Heating load: a winter outage can stop a furnace blower, boiler pump or heat pump. List what your heat needs to run before choosing a generator or battery.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in Ketchikan
By our rough estimate each kW of panels makes about 710 kWh a year in Ketchikan (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Ketchikan Public Utilities’s 2024 average of 12.48¢, that is about $89 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: June is the sunniest month at 4.58 and December the dimmest at 0.35, a 13.2-to-1 gap, so a battery or a bigger system helps in winter.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. The federal station list shows few or no public chargers listed under Ketchikan, so a home charger matters more here: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Ketchikan building or permitting department, or from Ketchikan Gateway County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Ketchikan, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Alaska guide lists the state licensing rules.

Ketchikan energy FAQ
Who is my electric company in Ketchikan?
Federal data lists Ketchikan Public Utilities as the main utility serving Ketchikan Gateway County. Small areas can be served by a different company or a co-op, so confirm on your bill.
How much power will solar make in Ketchikan?
About 710 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 4,260 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Will a home battery keep my heat on in an outage?
It can keep a furnace blower, boiler pump or a heat pump running for a while, but long cold outages drain a battery fast without solar to recharge it. Pair it with a generator or wood or propane heat if outages here run for days.
Do I need a permit for solar or a generator in Ketchikan?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
